Muslims must advocate for a more tolerant world

A pig's head was left outside a Quebec City mosque this week with a note saying, "Bon appetit".

Another troubling incident took place in London, Ontario where police said a woman wearing a Canada Day t-shirt attacked a Muslim woman, who suffered minor injuries.

Her assailant reportedly punched and spat on her and pulled her hijab.

It is, of course, intolerable that after any attack deemed Islamist terror, there should be a backlash against blameless individuals who are recognizably Muslim, either because of how they look or where they worship.
